WATER CONTAINER WITH HEATING COILS Filed NOV. 13, 1948 INVENTOR. zfdjE/fl Ma a/aka latented Ma 23, 1950 UNITED STATES PATENT OFFICE 2,508,794 WATER CONTAMR WITH HEATING COILS Joseph Mosciaro,'Englewood, N. 3. Application November 13, 1948, Serial No. 59,829 1 Claim. (Cl. 122-18) This invention relates to containers for heating water and the like and has particular reference to a container which is constructed and arranged for circulation of the water in close proximity to the heating flame or element so as to efiect rapid raising of the temperature of the water.

The invention has for an object the provision of a container having a central well depending from the bottom wall and horizontally disposed coils disposed in surrounding relation with the well adjacent the bottom wall and which coils open through the bottom wall to efiect circulation of the water in the container and the rapid heating thereof.

Another. object of the invention is to provide a water container having a recessed bottom wall and horizontally arranged coils disposed in the recess below the bottom wall and opening therethrough for eil'ecting rapid raising of the temperature of the water.

Still another object of the invention is to provide a water container of the indicated character in which one of the coils is connected with the central well adjacent the bottom thereof and opens upwardly through the bottom wall of the container for providing a circulation of the water from the well through the coil and upwardly into the container.

'With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is a view in elevation of a water container constructed in accordance with the invention and illustrating the same partially in section to show the underlying parts.

Fig. 2 is a horizontal sectional view therethrough taken approximately on line 22 of Fig. 1.

Fig. 3 is a bottom plan view thereof.

Referring to the drawings by characters of reference, the wate container is of any desired configuration having a bottom wall it, a peripheral wall I! and a cover l2 secured on the peripheral wall in any desired manner.

The bottom wall I is located upwardly from the bottom edge of the peripheral wall II and depending centrally therefrom is a cylindrical extension i 3 defining a central well which opens upwardly into the container. Located within the annular space surrounding the cylindrical extension I 3 are concentrically arranged annular through the outlet tubes.

coils l4, l5 and it which are disposed in a plane upwardly therethrough. The coils may be provided with any desired number of outlet tubes 11 and as illustrated, each of the coils has three such tubes which are located degrees apart. In addition to the outlet tube II, the outermost coil I6 is connected with the cylindrical extension l3 by means of a plurality of radially disposed branch tubes |8 having their outer ends curved upwardly and connected with the under side of said coil while the inner ends thereof open into the tubular extension l3 adjacent the bottom wall I9 thereof. I

Constructed in this manner the recess defined by the bottom wall It and the lower portion of the peripheral wall II of the container serves to entrap the heat from the heating flame or element below the bottom wall and about the tubes located in said recess. The intense heat created by the heating flame or -element in the recess surrounds the coils to produce a rapid heating and circulation of the water therein which passes upwardly through the outlet tubes i! into the container. Furthermore, the heating of the water in the outermost coil it produces a circulation of the water from the extension i3 through the branch tubes l8 and thence through the said coil and into the container What is claimed is:

In a water heater, a container including a peripheral wall and a bottom wall connected with the peripheral wall in spaced relation above the bottom rim thereof, a centrally arranged cylindrical extension depending from said bottom wall defining a central well having a closed bottom wall and having its upper end opening through the bottom wall of the container and with the bottom wall of said extension being located substantially in line with the bottom rim of the peripheral wall of the container to thereby form an annular recess below the bottom wall of the container, and between the lower portion of the peripheral wall thereof and the said cylindrical extension, a plurality of coils located in said recess and extending annularly about said cylindrical extension in spaced relation below the bottom wall of the container, outlet tubes connected to said coils respectively at circumferentially spaced locations and having their upper ends opening through the bottom wall of the con- 3 hineriorcirculstinzthewsterinthecoflsupwsrdlythrcushthooutlettubessndintothe container. andbranchtubes connectedto one of saidooilsandtossidcylindricalextensionat eiroumferentially spaced locations and opening 5 into said cylindrical extension adjacent the bottomthereofand sttheirimperendsopeninginto said coil for circulation of the water from said cylindrical extension through said branch tubes and coil and upwardly into the container.
